In this scenario, the Volume Activation and Management Tool (VAMT) is used to activate Key Management Service (KMS) clients on either Core Network or Isolated Lab computers. By default, volume license editions of Windows Vista®, Windows® 7, Windows Server® 2008 or Windows Server 2008 R2, and Microsoft® Office 2010 use KMS for activation. KMS client keys are already installed in volume license editions of these products. You do not need to enter a key to activate a product as a KMS client, unless you are converting a MAK-activated product to KMS activation. For more information, see Install a KMS Client Key.

The procedure described below assumes the following:

  1. Open the VAMT Microsoft Management Console (MMC) snap-in.

  2. Select the product(s) to be activated by selecting individual products in the product list in the center pane.

  3. Right-click the selected product(s) to display the context-sensitive Actions menu, or choose from the Action menu on the top menu bar, or choose from the Selected Items menu from the right-hand pane.

  4. On the menu, click Activate and then KMS Activation to display the Configure KMS host and port dialog box.

  5. Select one of the two activation options:

    • Auto-Discover KMS host using DNS. VAMT will instruct the computer to query the Domain Name Service (DNS) to locate a KMS host and attempt activation. If the client contains a registry key with a valid KMS host, that value will be used instead.

    • Use specific KMS host and port. For environments which do not use DNS for KMS host identification, VAMT will set the specified KMS host name and KMS host port on the target computer, and then instruct the computer to attempt activation with the specific KMS host.

  6. If you are activating products that require administrator credentials different from the ones you are currently using, select the Use Alternate Credentials check box.

  7. Click OK.

  8. The VAMT will display the Activating products dialog box until it completes the requested action. If you selected the Alternate Credentials option, you will be prompted to enter the credentials prior to this dialog.
